REGULATING-VALVE FOR LUBRICATORS.

SPECIFICATION forming part of Letters Patent No 761,425, dated May 31,I904. Application filed July 11,1902. Serial No. 115,128. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. SULLIVAN, a citizen of the United States,residing at Windsor, county of Essex, Province of Ontario, Canada, haveinvented a certain'new and useful Improvement in Regulating-Valves forLubricators; and I declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart towhich it pertains to make and use the same, reference being had tothe'accompanying drawings, which form a part of this specification.

This invention relates to lubricators, and has for its object animproved valve attachment arranged to control the passage through whichthe oil escapesfrom the oil-cup of the lubricator into the sight-feedglass. .In theopera tion of this invention the valve is closed when thesteam is throttled and is open only when steam is free to pass throughthe cut-off at the throttle-valve of the engine.

In the drawings, Figure 1 shows a lubricator with the valve-actuatorattachment. Fig. 2 is avertical section through the attachment.

A indicates theoil-cup of a lubricator, of which lindioates thesight-feed. glass, connected to the oil-cup .by a fitting 2, throughwhich there is a passage for the flow of oil from'thecup into thesight-feed glass. .This passage is controlled bya needle-valve 2, whosestem is arranged to be actuated by the device embodying this inventionin either ofthe ways hereinafter described. r

In Fig. 2 the stem 3 of the needle-valve 2* is provided with a thread 2"and is inserted through a threaded sleeve 7, which is secured in anysuitable way to a diaphragm 8, that divides a chamber 4. The upper partof the chamber a is arranged to receive steam through a steam-inlet 5from steam-pipe 5, into which steam is admitted when the throttle 5 isturned to admit the steam to the engine. The casing of the chamber 4 issecured to the fitting'Q by a two-part coupling-nut 6, that screws ontothe fitting 2' and onto which a nipple of the' casing screws. The sleeve7 is concentric'with the coupling 6 and with the nipple 6*, andprovision is made that it may have a motion longitudinal of its axisthrough the walls of the chamber and through the coupling 6. The 'stem 3of the valve 2 projects through the diaphragm 8, and below the diaphragm8 it is surrounded by anadjusting-spring 9, that is seated in a nipple9, that forms part of the casing of the chamber 4. The lower end of thenipple 9 is closed byaperforated adjusting-nut that isexternallyscrew-threaded to engage in internal threads of the nipple 9and is internally threaded to engage/with the external threads of astop-sleeve l0. The hollow nut 11- bears against the lower end of thespring 9 and is employed to-adjust the tension of the spring 9, theupper end of which bears against the lower face of the diaphragm 8 or,as shown in the drawings, against the lower face of a nut by which thediaphragm 8 is held to the sleeve 7. The .spring 9 coacts with thediaphragm to drive the Valve 2 to its seat, fromwhich it is forced bysteam-pressure acting against the upper face of the diaphragm 8. Thesleeve 10 is adjustable through the nut 11 and is arranged toregulatethe amount of opening possible for the valve. The valve and itsstem are actuated by the diaphragm, whichengages with-the stem throughthe intermediate part or sleeve 7, and the stem 3 can be adjusted in thesleeve 7 by turning the stem on its own axis, and thereby running thethread ed part 2 of the stem along the threaded part of the sleeve- WhatI claim is' i 1. In combination with a lubricator, a detachablevalve-actuator, having in combination a casing provided with means toattach it to the lubricator, a diaphragm spanning the casing, a valveprO ectmg from the casing, 'a

valve-stem therefor passing through the 'cas- I ing and through thediaphragm, a sleeve secured to the diaphragm embracing the valvestem andadjustably secured thereto,a second sleeve-also embracing the valve-stemand passing through a threaded nipple, a threaded nipple engaging athread ed opening in the casing embracing the second-named sleeve on thevalve-stem and ad ustably secured to said sleeve, a spring surroundingthe valve-stem,

engaging against the diaphragm and against the threaded nipple, andmeans for admitting actuating fluid into the casing on the side of thediaphragm opposite said spring, substantially as described.

2. In combination with a lubricator, a detachable valve-actuator havingin combination a casing provided with means to attach it to thelubricator, a valve projecting from the casing, a diaphragm spanning thecasing, a valve-stem therefor provided with a threaded part and passingentirely through the casing and through the diaphragm, a threaded sleevesecured to the diaphragm embracing the valve-stem and with its threadedpart engaging the threaded part of the valve-stem, a second sleeve alsoembracing the valve-stem, a threaded nipple engaging a threaded openingin the casing, engaging around the secondnamed sleeve on the valve-stemand adjust,

ably secured thereto,a spring engaging against the diaphragm, and meansfor admitting actuating fluid into the casing on the side of thediaphragm opposite said spring, substantially as described.

3. In combination with a lubricator, a detachable valve-actuator, havingin combination a casing provided with means to attach it to thelubricator, and with means for the admission of actuating fluid, adiaphragm spanning the casing, a valve external to said casing, avalve-stem therefor passing through the attaching means through thecasing and through the diaphragm, a sleeve secured to the diaphragm andhaving a reciprocatory motion through the casing and through saidattaching means, means for adjustably securing the sleeve to thevalve-stem, a second sleeve secured to a Wall of the casing and engagingaround the valve-stem, means for adjusting said second sleeve withrespect to the wall of the casing, and a spring engaging against thediaphragm, substantially as described.

4. In combination with a lubricator, a detachable valve-actuator, havingin combination a casing, means for attaching the casing to thelubricator, a diaphragm spanning the easing, a valve external to thecasing, a valvestem therefor passing through the diaphragm and throughthe casing at'both sides of the diaphragm. a reciprocatory sleevesecured to the diaphragm embracing the valve-stem and adjustably securedthereto and having a recip rocatory motion through the casing, a secondsleeve on the opposite side of the diaphragm from the first-mentionedsleeve, arranged to guide but allow free reciprocation of the valvestemtherethrough, means for adjusting said sleeve with respect to thediaphragm, a spring arranged to bear against the diaphragm, and meansfor adjusting the tension of said spring, substantially as described.

5. In combination with a lubricator, a detachable valve-actuator havingin combination a casing provided with means for attaching it to thelubricator, and with means for admitting actuating fluid thereinto, adiaphragm spanning said casing, a sleeve secured to said diaphragmreciprocating through said casing and through the attaching means, avalve actuated by said sleeve, a spring reinforcing said diaphragm,concentrically arranged means for independently adjusting from outsidethe casing the relation between the valve and the diaphragm and-therelation between the diaphragm and the reinforcing-spring and thevibratory limits of said diaphragm, substantially as described.

6. In combination with a lubricator, a casing provided with afluid-inlet at one side thereof, a diaphragm secured in said casing, asleeve secured to the diaphragm. sliding through and guided by a portionof said casing, a spring bearing against the diaphragm, a nut adjustablysecured to the casing and bearing against the spring, anindependentlyadjustable stop for the diaphragm carried by said nut, avalve-stem projecting through said stop and in threaded engagement withthe sleeve on the diaphragm, and means on the outer end of said stem forturning the same, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.

CHARLES A. SULLIVAN.
